relative turning of the complemental nuts or bolts which provide fastenings.

,An object of the present invention is to provide a tool which will enable one man to remove a dust pan froinbeneath an engine in an automobile, and which is particularly adaptable for removing the dustpans from Models A and AA of Ford cars and trucks, although it may be equally applicable to other types ofmotor vehicles, machines and various other installations.

A further object of the invention is to en able one man to perform the necessary work of removing fastenings comprising nuts and bolts without the expenditure of a great deal of unnecessary labor and time.

Briefly stated, the tool embodies a pair of peculiarly constructed wrenches and ,a clamping socket member constructed to co-operate with the wrenches for holding them from independent and-relative movement when the Wrenches are applied to the heads vof bolts,-

nuts or the like.

A further feature of the present invention is to provide a tool set of this charactenvthe,

independent units of which may serve inclividually as wrenches or for otherpurposes so that the units of the set may thus not only co-operate to produce, the desired novelre- ;sult, but may also be independently used for various purposes and to take the place of separate and independent tools which must now be resorted to. i I

With the foregoing and other objects in view, the invention will be more fully de-' scribed hereinafter, and will be more particularly pointed out in the claims appended hereto. v

In the drawings, wherein like smybols refer to like or corresponding parts out the several views,

Figure 1 is a fragmentary perspective view of the inner side of a side frame member of a motor vehicle showing a dust pan secured thereto, and showing the tool of this th'roughinvention in position with relation to the parts. V

Figure 2 is a vertical section taken through the tool as applied and shown on the section line 2-2 of Figure 1.

Figure 3 is a similar section taken on the line 3-3 of Figure 1 and showing in section the-intermediate portion of the tool with the clamp applied thereto.

Figure 4 is a detail enlarged perspective view of the lower unit of the tool.

Figure 5 is a similar View of the upper unit of the tool, and

Figure 6 is a detail perspect1ve view of the V clamp for binding the units of Figures 4 and 5 together as shown in Figure 1.

Referring now to the drawings, 10 designates one of the side members of a motor vehicle at theforward end thereof. The dust pan 11 adapted to extend at oppositesides and beneath the engine is secured in the usual mannerv tothe lower channel flange of the side member 10 by bolts 12 which project downwardly through the side member 10, binding nuts 14 being threaded upon the lower ends of the bolts 12 to accomplish this purpose.

Considerable difliculty has been occasioned in the removal of the bolts 12 and nuts 14 incident to the fact that the nuts 14 become rusted upon and otherwise grip the bolts 12 with sufficient frictional engagement as to turn the bolts and nuts as a unit in the side member 10; v

It is also well known that it is practically impossible for one man to hold a wrench on the head of the bolt 12 and simultaneously apply and operate a wrench on the nut 14 on account of the body structure of the vehicle and the inaccessible positions of the innervor channel Side 036 the member 10 and the exterior lower side of the dust pan 11.

The present invention provides a tool or tool set which is adapted to engage a pair of adjacent bolts 12 and hold them rigidly from turning so that one man may easily remove the bolts '12 by operating a wrench or the like upon the nuts 14 disposed beneath the vehicle. The device of the invention comprisesa lower arm which is in the form of an elongated shank provided with an offset wrench head 16 shown in the present instance as of the fixed type, although any suitable construction of head may be provided for engaging the head of one of the bolts 12.

The opposite end of the arm 15 is also provided with a wrench head 17 which is ofl'- set from the arm 15 into substantially the plane of the head 16 so that when, as shown in Figure 1, the lower unit 15 is placed within the side frame member 10 and with the wrench heads 1.6 and 17 extending downwardly, the arm 15 is supported substantially horizontally and in spaced relation above the bottom flange of the side member 10.

The tool also comprises an upper arm 18 which may be of substantially the same length as the arm 15, and the arms 15 and 18 are of uniform thickness and width throughout substantially their entire lengths so that the upper arm may seat in face to face engagement upon the upper face of the lower arm 15 and wherein the arms may be overlapped to various degrees depending upon the spacing apart of the bolts 12. The arm 18 is provided at one end with an offset wrench head 19, which offset equals substantially the offset of the wrench head 17 of the lower arm 15 plus the thickness of the arm 15 so that the head 19 may seat over the head of a second adjacent bolt 12, as shown in Figure 1, and maintain the contacting faces of the arms 15 and 18 in engagement throughout their overlapping portions.

The opposite end of the upper arm 18 is provided with an oppositely offset wrench head 20 which serves as a means for receiving the fingers in adjusting and positioning the upper arm 18 as it is applied to the second bolt 12, and to facilitate the swinging of the arm 18 into proper alignment with the arm 15. This projection 20 may be in the form of a wrench head so that the arm 18 may have further use when used alone and so that the tool may thus be used in the ordinary manner of wrenches and may be of special sizes to fit certain Vehicles or machines. The same is true of the head 17 of the lower arm 15 as its chief function in the set is to provide a foot piece to hold the arm 15 horizontal when in position.

The clamp or clamping means of the set for holding the arms 15 and 18 in overlapping superposed relation comprises a saddle plate 21 which is of substantially inverted U-shape and of suitable width and depth so as to engage with a fairly snug fit over the overlapping arms 15 and 18 to maintain the same in superposed alignment. The saddle 21 is provided at its upper closed edge with an upstanding threaded stem or bolt 22 upon which is threaded an elongated nut 23 having a rounded upper end 24 providing a bearing surface adapted to engage against the underside of the top flange of the side member 10 when the elongated nut 23 is turned upward- 1y on the stem or bolt 22.

The nut 23 thus comprises a clamping element adapted to exert a counter pressure from the upper flange of the side member against the saddle 21 for binding the latter securely on the arms 15 and 18 and causing the head or foot piece 17 of the lower arm 15 to frictionally bind against the lower flange of the side member 10. The clamping device is thus adapted to hold the arms 15 and 18 from swinging out of the side member 10 and for thus holding the nuts 12 engaged by the nut heads 16 and 19 from turning when pressure is applied to the lower ends of the bolts 12.

Thus, when the bolt heads 12 are securely locked against turning by the tool of this in vention, a wrench may be applied to the nuts 14 on the lower ends of the bolts for turning the nuts and the user may thus exert his full attention and pressure on the nuts. It is of course understood that the heads 16 and 19 may be engaged equally as well with the nuts 14 should the latter be disposed upwardly or within the channel member 10. It is also apparent that it is not necessary to have a channel member with which to operate the tool as it is only essential to have opposed flanges or parts for the clamping nut 23 and saddle 21 to bear against.

It is obvious that various changes and modifications may be made in the details of construction and design of the above specifically described embodiment of this invention without departing from the spirit thereof, such changes and modifications being restricted only by the scope of the following claims:
